Large Hadron Collider(LHC) Could Detect Extra Dimensions

A recent paper published in Physics Letters B has raised the
prospect that the LargeHadron Collider (LHC) could mark a discovery that would
put its earlier achievements with the Higgs Boson in the shade. The authors of
the recent published paper propose it could spot mini black holes. Such a
discovery would be a matter of massive importance on its own, but might be a
sign of even more significant things. Few notions from theoretical physics
capture the public imagination as much as the “many-worlds theory,” which
suggests an infinite number of universes that vary from our own in ways large
and small. The notion has delivered great fodder for science fiction novelists
and comedians. Nevertheless, according to Professor Mir Faizal from the
University of Waterloo, "Normally, when people think of the multiverse,
they think of the many-worlds interpretation of quantum mechanics, where every
possibility is actualized," he told Phys.org. "This cannot be tested
and so it is philosophy and not science." Nonetheless, Faizal reflects the
test for a different type of parallel universes nearly within our reach.

Faizal says “What we mean is real universes in extra
dimensions. As gravity can flow out of our universe into the extra dimensions,
such a model can be tested by the detection of mini black holes at the LHC.”

The notion that the universe may be full with minute black
holes has been projected to clarify puzzles such as the nature of dark matter.
However, the energy required to generate such objects relays on the number of
dimensions the universe has. In a predictable four-dimensional universe, these
holes would need 1016 TeV, 15 orders of magnitude beyond the capability of the
LHC to create. String theory, on the other hand, suggests 10 dimensions, six of
which have been wrapped up so we can't observe them. Efforts to model such a
universe propose that the energy required to make these minute black holes
would be a great deal smaller, so much so that some researchers believe they
should have been spotted in experiments the LHC has already run.

So if no discovery, no string theory? Not according to Mr. Faizal
and his co-authors. They claim that the models used to forecast the energy of
the black holes in a 10-dimensional universe have left out quantum twist of space-time
that changes gravity marginally.

Whether this distortion is actual is a swiftly developing
question, but if it is, the paper claims that the black holes will have energy
levels considerably smaller than in a four-dimensional universe, but about
twice as large as that noticeable for any test run so far. The LHC is aimed to
reach 14 TeV, but so far has only gone to 5.3 TeV, although the paper reflects
the holes might be lurking at 11.9 TeV. In this circumstance, once the LHC touches
its full capacity, we should find them.

Such detection would determine the micro scale deformation
of space-time, the presence of extra dimensions, parallel universes within them
and string theory. If discovered at the right energy levels, the holes would approve
the group's explanation of a new theory on black hole behavior named gravity's
rainbow, after the significant novel. Such an amazing quadruple exposure would alter
physics, even though the scientists are already considering the most likely errors
in their work if the holes prove elusive.
